2 Claims. or. 20-36 This invention relates to fasteners-of'the turnbutton type for securing in place on auxiliary doors (or windows) the removable insert glazed or screen sections.

Heretofore the fasteners for the insert glazed or screened sections for auxiliary doors and/ or windows have involved a turnbutton fastener on the frame section positionable toextend one end overlapping the insert section. These turnbutton fasteners have been rotatably mounted either on the face of the frame section or recessed therein and secured to a stud-pin journaled in the frame section with the 'kerfed end of the stud-pin exposed on the face of the frame section for the application of a screw driver. In the former arrangement the turnbuttons always are exposed as obstructions on the face of the door or window. In this latter arrangement the side edges of the vertical stiles of the insert sections have to be slotted to receive the ends of the turnbuttons.

The main objects of this invention are to provide an improved type of turnbutton fastener for;securing the glazed or screened insert sections in place on the auxiliary door or windows supporting section; to provide an improved fastener of this kind which is exposedly recessed in the face of one of the sections for turning, merely by the application of ones fingers; to provide a fastener of this kind with improved means for yieldably retaining it in any adjusted position; to provide a turnbutton fastener of this kind with improved means for protectingthe section material from excessive wear, especially when the sections are made of wood; and to provide an improved fastener of this kind which is inexpensive to manufacture, easy to attach, and of ornamental charactenj Illustrative embodiments of this invention are shown in'the accompanying drawings, in which:

The essential concept of this invention involves a lessthan-circular element of arcuate cross-section formed with an upset radially-disposed finger-grip portion and so journaled in a metal-lined circular depression in adjacent parts of the separable sections of a combination auxiliary door or window that in one position of the fastener a peripheral wing-portion overlaps the adjacent face of the other section and in another position of the fastener the entire periphery is located inwardly of the adjacent perimeter of the section on which the fastener is mounted. I p

A turnbutton fastener 10 embodying the foregoing concept, for use with a supporting frame section 11 and an insert section 12 ofan auxiliary storm door (or Window), comprises an element 13 rotatively mounted in a circular depression 14 formed in and spanning abutting parts of the sections 11 and 12 and protected by a lining 15, the element 13 being held in place by a screw 16 with an interposed compression-friction washer 17.

The sections 11 and 12, of the hereinshown auxiliary storm door, are of conventional character. The supporting frame section 11, formed of the usual stiles 18 and top and bottom cross pieces 19, and the insert section 12, formed of the usual stiles 20 and top and bottom cross pieces 21, are conventionally dimensioned, contoured, and shouldered so that the insert section 17 fits into the frame section 11 in the plane thereof. and is held in place by pairs of the fastener elements 13, generally secured to the stiles of the frame section 11; The insert section 12 may be either glazed or screened, in the conventional manner, and interchangeablypositionable in the frame section 11 so that it serves both winter and summer needs.

Two slightly differently contoured forms of fastener elements 13 are shown-Figs. 2-5; and Figs. 6-9 respectively. However, the'two adapt ation s 'are'mounted and function in precisely the samenianner. Preferably the elements 13 are metal stampings, each of less-than circ u lar form, arcuate in cross-section, and having a central portion radiallyupset from the concaveface to form a finger-grip 22 extendingacross the element from a wing-portion 23 g V 1 a In, the simpler and '-less-expensive-to-manufacture element 13 (Figs. 2-5 the upset finger-grip 22 is rfori'nedof single parallel flanges terminating at a pointdiametrically opposite the wing-portion 23, which overlaps the insert section 12. The extremities 24 of the flanges forming the finger-grip 22 and the extremities 25 of the wing-portion 23 are so disposed that when the element 13 is turned to retract the wing-portion 23 from overlapping the insert section 12, the respective extremities 24 and 25 on one side of the element 13 are positioned Within the inner face of the frame section stile 18. This permits the placing and/ or removing of the insert section 12.

The slightly more ornate element 13 (Figs. 69) is more nearly a complete disk having only a small portion cut away along a line 26. This line 26 is spaced from the axis of the element 13 a distance equal to that from the axis of the element 13 to the inner face of the stile 18 on which the element 13 is mounted. In this adaptation the upset finger-grip 22 is formed by doubled-over parallel flanges (Fig. 8) rather than the single flanges of the other adaptation (Fig. 4),and terminates short of the edge 26. To further enhance the ornamental effect of this element 13, a chevron-like embossment 27 is formed in the peiipheral wing-section 23.

In order to locate these elements 13 below the faces of the stiles 18 and 20 of the frame and insert sections 11 and 12, the circular, concave depressions 14 are formed in the stiles 18 and 20 at longitudinally-spaced points, as indicated in Fig. 1. Such depressions 14 would be cut with a specially-formed tool, where the sections 11 and 12 are made of wood or solid metal. If these sections were made of hollow metal, the depressions 14 could be obtained by deforming the metal. As is most clear from the figures, the depressions 14 are positioned soth'at the major part of each is in the frame section stiles-1'8 The part of the depression 14 in the insert section stiles needs to be merely enough to insure a reasonable overlap of the wing-portion 23 of the fastener elements 13.

When the frame section 11 is formed of wood, the thin metal lining 15, concaved to fit in the depression 14, is fixed in that part of the depression 14 located in the frame section stiles 18. Preferably an integral turnover tab 28 is formed along a chord of the liner 15 to abut against the inner face of the stiles 18 (Figs. 3 and 7). These liners 14 may be secured in place in any suitable manner; by several small brads through the face of each liner and/ or through the tabs 28, and/or by the use of a suitable adhesive.

The pivoting screw 16 here is shown as a conventional wood screw. The washer 17 may be rubber or any comparable substitute which will tend to yieldingly retain the elements 13 in any adjusted position.

Among the more apparent advantages of this improved type of turnbutton fastener are; exposed ornate appearance; operable by mere pressure of the fingers; flushed position permits stacking for storage or transport; constant tension of washer prevents rattle of loose parts, compensates for variations in the thickness of the frame and insert materials, and precludes backing up of screw.

The manner of operating of such an improved fastener is believed to be so obvious from the foregoing description as to require no further explanation.

Although but two adaptations of invention are herein shown and described it will be understood that details of the structure may be altered or omitted without departing from the spirit of the invention as defined by the following claims.

I claim: r
